Modelling Energy Loss in Buildings with Rotating Rooftop Restaurants

Rotating rooftop restaurants offer panoramic city views and a unique dining experience, but they also introduce engineering and energy-efficiency challenges. The constant movement of the structure, combined with its elevated and often glass-heavy design, can affect thermal performance, ventilation, and Energy Performance Certificate (EPC) modelling accuracy.

EPC Challenges with Active Phase-Change Wall Inserts

Active phase-change wall inserts are a cutting-edge building technology designed to regulate indoor temperatures by absorbing, storing, and releasing heat as they transition between solid and liquid states. By actively controlling the timing of these phase changes through embedded systems, buildings can significantly reduce heating and

EPC Ratings for Homes with Subterranean Greenhouses

Subterranean greenhouses — also known as walipini or pit greenhouses — are partially or fully built below ground level to leverage the earth’s stable temperature for year-round growing. These structures are gaining popularity among eco-conscious homeowners for their energy efficiency, reduced heating needs, and unique integration

Impact of Helio-Tracking Facades on EPC Cooling Projections

Helio-tracking façades are advanced building envelope systems designed to adjust their orientation or shading elements in response to the sun’s position. By optimising solar exposure throughout the day, these façades can reduce cooling loads, improve daylighting, and enhance occupant comfort. While these systems offer clear environmental

EPC Limitations for Urban Buildings with Dense Vertical Gardens

Vertical gardens — also known as green walls or living façades — are increasingly popular in urban architecture for their aesthetic appeal, biodiversity benefits, and ability to improve air quality. They can also influence a building’s thermal performance by providing shade, reducing heat absorption, and moderating

How EPC Treats Solar-Reflective Liquid Glass Roof Coatings?

Solar-reflective liquid glass roof coatings are a modern roofing innovation designed to reduce heat absorption by reflecting a significant portion of solar radiation. By lowering roof surface temperatures, these coatings can reduce the cooling demand of a building, enhance indoor comfort, and potentially improve its Energy

EPC Modelling for Buildings with Seasonal Inflatable Insulation Panels

Seasonal inflatable insulation panels are an innovative approach to improving a building’s thermal performance while maintaining flexibility throughout the year. Unlike fixed insulation, these panels can be deployed during colder months to retain heat and deflated or removed during warmer months to allow natural cooling. This

Assessment Challenges for EPC in Buildings with Combined Biofuel and Solar Thermal Systems

Buildings that integrate biofuel-based heating with solar thermal systems provide sustainable energy solutions by combining renewable heat sources with conventional systems. However, this hybrid approach introduces unique challenges for Energy Performance Certificate (EPC) assessments due to variable energy contributions, system interactions, and performance uncertainties. 1. Understanding

EPC Challenges in Buildings with Combined Passive Solar and Active Mechanical Systems

Buildings that integrate passive solar design—such as south-facing glazing, thermal mass, and natural ventilation—with active mechanical systems like HVAC and heat pumps provide both energy efficiency and comfort. However, this combination presents unique challenges for Energy Performance Certificate (EPC) assessments. 1. Understanding Combined Passive-Active Systems Definition:

EPC Considerations for Buildings with Multiple Interconnected Courtyards

Buildings with multiple interconnected courtyards offer enhanced natural lighting, ventilation, and aesthetic appeal. However, these open spaces introduce complexities for Energy Performance Certificate (EPC) assessments due to unique airflow patterns, solar gains, and heat loss behaviors. 1.
